WILLIAM A. GIBSON, OF DETROIT, MICHIGAN.

DISK WHEEL;

Application filed May 27, 1922. Serial No. 564,084.

T 0 all whom it may concern:

Be it known that I, VVILLIAM A. GIBsoN, a citizen of the United States,residin at Detroit, county of Wayne, State of Michigan,.have inventedcertain new and useful Improvements in Disk Wheels, of which thefollowing is a specification.

This invention relates to improvements in disk wheels.

The object of the invention is to provide a disk wheel structure whichwill be simple and inexpensive to manufacture and yet very strong inuse.

A further object is to provide a disk wheel structure in which the webof the wheel is made u of sections with an effective and simple ointtherebetween.

Objects pertaining to details and economies of construction andoperation will definitely appear from the detailed description tofollow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification' The invention is clearlydefined and ointed out in the claims.

A structure whic is a preferred embodiment of my invention is fullyillustrated. in

the accompanying drawings, forming a part of this application, in which:

Fig. I is an outside elevation view of a wheel embodying the features ofmy invention, with the rim demounted.

Flg. II is an enlarged detail sectional view of such wheel taken on line2-2 of I. v 1g. III is an enlarged detail sectional view of the seamedretaining rib taken on line 3-3 of Fig. I.

Fig. IV is a detail perspective view of one of the sections or segmentsof the web of the wheel.

Fig. V is an enlarged detail elevation view of the inner portion of oneof the wheels showing the arrangement of the joint memher and itsconnection to the rim.

Fig. VI is a detail sectional view taken on line 6-,6 of Fig. V, showingthe construction of the seamed joint and the connection to the fixedrim.

Fig. VII is a detail sectional view similar to Fig. II, of a modifiedform of the wheel in which the disk is conformed into doubleconcavo-convex or concentric corrugation formation to increase thestrength and improve the a pearance.

Fig. V II is a detail perspective view of clearly side of the wheel.

one ofthe sections of the web of this modification.

In the drawing similar numerals of refof angular sections 6,-see Fig.IV, the edges of which are joined together bythe seamed sheet metaljoint member 7 which is folded upon itself at 8, 8 and folded outwardlyat 9, 9 and inserted between the said members engaging the edges of thesection 6, as appears in Figs. III and V. When the w eel has been thusassembled together, the fixed rim 11 is put in place and riveted orotherwise secured to the flanged outer edge of the web 5, as seen at 61,the same being secured in place by rivets 62.

The only difference between the structure of Fig. II and Fig. VII is aconcentric corrugatmg or double concavo convex curving of the web of thewheel as seen at 5' and 6' in Fig. VIII. The joint member 7 is suitablyconformed thereto. The special form shown in Fig. VII accommodates thevalve stem 13 so that it is accessible from the outmetal in a stampingpress and the flan e 61 turned at the outer end thereof an the inner endsuitabl perforated to accommodate the flange bolt 4. The finishingseamed joint rib 7 is then inserted in place and the entire wheelconformed and the flanged outer end riveted to the fixed rim of the.

wheel, the same being of suitable form to receive the demountable rim..The fixed rim might be suitably flan ed to receive a tireof theclincher type. T e form of the fixed rim is not material to myinvention.

I desire to claim the invention broadly and in its specific formillustrated, as pointed out in the appended claims.

the

' ters Patent, is:

Having thus described my invention, what I claim as new and desire tosecure by Letof sheet metal with an inturned and outturned portion toform grooves at each side to retain and engage the edges of the saidsections, filler disks between the hub flanges to embrace the inner endsof the said wheel, and a fixed rim riveted to the outer flan e of thesaid wheel, allsubstantially as described.

2. In a disk wheel, the combination of a hub with suitable flanges, aweb for the wheel made up of sheet metal sections,

seamed joint members therebetween formed 1 of sheet metal with aninturned and outturned portion to form grooves at each side to retainand engage the edgesof the said sections, and a fixed rim'secured to theouter flange of the said wheel, all substantially as described. f

3. In a disk wheel, the combination of a hub with suitable flanges, aweb for the wheel made up of concentrically corrugated sheet metalsections, seamed jo nt members therebetween formed of sheet metal withan WILLIAM A. GIBSON. [a 5.

I have hereunto set.
